General annotation (Comments)
| Function | Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides. |
| Catalytic activity | 2'-deoxyribonucleoside diphosphate + thioredoxin disulfide + H2O = ribonucleoside diphosphate + thioredoxin. |
| Enzyme regulation | Under complex allosteric control mediated by deoxynucleoside triphosphates and ATP binding to separate specificity and activation sites on the M1 subunit. The type of nucleotide bound at the specificity site determines substrate preference. It seems probable that ATP makes the enzyme reduce CDP and UDP, dGTP favors ADP reduction and dTTP favors GDP reduction. Stimulated by ATP and inhibited by dATP binding to the activity site By similarity. |
| Pathway | |
| Subunit structure | Heterodimer of a large and a small subunit. |
| Sequence similarities | Belongs to the ribonucleoside diphosphate reductase large chain family. Contains 1 ATP-cone domain. |
